♔♔♔ The Jeep Wrangler TJ horn relay is a electromechanical device that switches battery current to the horn when the horn switch grounds the relay coil. The horn relay is located in the Power Distribution Center (PDC) in the engine compartment. The horn relay is a International Standards Organization (ISO) micro-relay. The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.

♔♔♔ Jeep Liberty KJ Series equipped with the premium speaker package have a amplifier choke and relay (1). The amplifier choke and relay is mounted to the lower instrument panel above the pedals and towards the instrument panel center stack. The amplifier choke and relay should be checked if there is no sound output from the speakers. The amplifier choke and relay can not be repaired or adjusted and, if faulty or damaged, the unit must be replaced.

♔♔♔ The Dodge Ram front fog lamp relay is located in the Power Distribution Center (PDC) in the engine compartment of the vehicle. The front fog lamp relay is a conventional International Standards Organization (ISO) micro relay (see below picture). Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. The relay is contained within a small, rectangular, molded plastic housing and is connected to all of the required inputs and outputs by five integral male spade-type terminals that extend from the bottom of the relay base. The front fog lamp relay cannot be adjusted or repaired and, if faulty or damaged, the unit must be replaced. The following picture shows the Dodge Ram front fog lamp relay diagram:

♔♔♔ The 1988 Jeep Cherokee, Comanche, and Wagoneer 4.0L engine series use an auxiliary fan. The auxiliary fan is controlled by a relay mounted on the left inner fender panel. When coolant temperature is more than 190°F/88°C, the radiator coolant temperature switch closes allowing current from the ignition switch to flow through the fan relay to ground activating the relay. When relay is activated, battery voltage is supplied to the fan causing it to operate. When coolant temperature is below 190°F/88°C, the radiator coolant temperature switch opens preventing the relay from being grounded and electric cooling fan from being energized.

♔♔♔ The Jeep Patriot and Jeep Compass are both introduced in 2007 and based on the DaimlerChrysler/GS platform. These vehicles are differentiated by their styling and marketing: The Patriot is a traditional four-door Jeep wagon, similar to the Cherokee, while the Jeep Compass is intended as a sporty crossover.
